Underdog bumpers are weights made of recycled rubber, they have an extremely homogeneous structure thanks to the new pressing technique, which allowed us to get a better final product.

Their main application is in weight training and training where the exerciser wants to reach maximum performance.

Due to the fact that they are made of rubber, they are not damaged when thrown, nor do they cause damage to the surface. The central ring is made of stainless steel, molded at the same time as the rubber in the same mold.

Bumper weights do not make noise when throwing and absorb the fall without high bounce., they are made in our molds and correspond to standard IWF dimensions, they are certified for over 21,000 throws.
